In an preview of the upcoming docu-drama, the mother-of-four says goodbye to her old life (including her cheating ex-husband Sugar Bear) and undergoes a gastric sleeve procedure to help kick start her weight loss.

“Honestly, when I first started losing weight, it was just being more active, being busy with the show and doing more things with Here Comes Honey Boo Boo,” she told In Touch. "I went from like a [size] 28 to a 16 — and these pants are a little too big!”

On the show, fans will also see Mama June upgrade her home, trade in the "sketti" for personal training sessions and complete a drastic makeover that leaves her daughters in complete shock.

"There is no way in hell that's you Mama," Pumpkin says in disbelief.
